4.4 Tyre tread depth and age of tyres
The law states that tyres must be replaced when the tread depth
gets to 1.6 mm.
Tyre manufacturers‘ recommendations
• Irrespective of their tread depth, tyres should be changed
every 6 years.
• Avoid hard impacts against curbs, potholes or other obstacles.
Tyres age even if they are selomly used or not at all.
The minimum tread depth gives you only the barest amount of safe
-
ty while driving. The following recommendations must be observed:
Safety limit in summer: 3.0 mm
Safety limit in winter: 4.0 mm
Tyres should never be exchanged from one side to the other,
i.e. from the right-hand side of the vehicle to the left-hand
side and vice versa.

Different tyre pressures
If the pressure is too low, this may cause overheating of
the tyre, possibly resulting in severe damage to the tyre.
If the tyre pressure is too high, this will lead to increased
wear and tear of the tread and may cause damage to the
wheel suspension.
For the correct inflation pressure, please refer to the table
„Tyre pressure values"
in the
chapter 14
on “Technical Data“
or the operating instructions for the basic vehicle.
